number-crunching n. common computations of a numerical nature, esp.
   those that make extensive use of floating-point numbers. the only thing
   fortrash is good for. this term is in widespread informal use outside
   hackerdom and even in mainstream slang, but has additional hackish
   connotations: namely, that the computations are mindless and involve
   massive use of brute force. this is not always evil, esp. if it
   involves ray tracing or fractals or some other use that makes pretty
   pictures, esp. if such pictures can be used as wallpaper. see also
   crunch.
